+## [0.10.0] - 2022-11-30
+
+[[#133]]: atomic read/writes rework to avoid deadlocks in Policies.
+
+### Changed
+
+- `Aggregate`:
+  - `apply_events` has been removed, and its default implementation moved to a method of `AggregateState`.
+- `AggregateManager`:
+  - `lock_and_load` acquires a lock, then loads into memory the AggregateState
+    preventing other atomic accesses. Dropping the AggregateState releases the resource.
+  - `lock` has been removed in favour of `lock_and_load`.
+  - `handle_command` does not return the AggregateState anymore. This avoids race conditions where the
+    returned state is already outdated, if another concurrent access has taken place at the same time.
+  - `apply_events` has been removed, and its default implementation moved to a method of `AggregateState`.
+  - `load` has been changed to return a `Result<Option<_>, _>`, to explicit expose errors.
+- `AggregateState`:
+  - new `lock` field, which contains the exclusive access guard created when `lock_and_load`ing.
+    All other fields are now private for better encapsulation.
+  - `new` takes no argument, and generates a new state with a random UUID.
+  - `with_id` generates a new state with the given UUID.
+  - `apply_store_events` applies the given list of Events on self.
+  - `set_lock` and `take_lock` methods to set and get the lock,
+    to use when overriding the AggregateManager functionality.
